This is an insane clickbait, and none of the comments seem to have read further than the title.
There are two metrics in the study:
> AI chatbots save time across all exposed occupations (for 64%–90% of users)
and
> AI chatbots have created new job tasks for 8.4% of workers
There's absolutely no indication anywhere in the study that the time saved is offset by the new work created. The percentages for the two metrics are so vastly different that it's fairly safe to assume it's not the case.
> Indeed, the reported productivity benefits were modest in the study. Users reported average time savings of just 2.8 percent of work hours (about an hour per week).

> Our main finding is that AI chatbots have had minimal impact on adopters’ economic outcomes. Difference-in-differences estimates for earnings, hours, and wages are all precisely estimated zeros, with confidence intervals ruling out average effects larger than 1%. At the occupation level, estimates are similarly close to zero, generally excluding changes greater than 6%.
